Defines S4 classes for single-cell genomic data and associated
information, such as dimensionality reduction embeddings, nearest-neighbor
graphs, and spatially-resolved coordinates. Provides data access methods and
R-native hooks to ensure the Seurat object is familiar to other R users. See

Key-validity function

Keys must be a one-length character vector; a key must be composed of one
of the following:<ul>
<li>An empty string (eg. &#8220;<code>''</code>&#8221;) where <code>nchar() == 0</code></li>
<li>An string composed of one or more alphanumeric values
 (both lower- and upper-case) that ends with an underscore
 (&#8220;<code>_</code>&#8221;); the first character must be a letter</li>
</ul>Keys that are not empty strings are validated with the regex
&#8220;<code>SeuratObject:::.KeyPattern()</code>&#8221;
